JOHN A. JOHNSON, or MADISON, WISCONSIN.

SULKYDFRANIE.

SECIFICATION forming part of Letters Patent No.. 319,264, dated June 2, 1885i.

Application filed March 2, 1885.

To @ZZ whom, it may concern:

Be it known that I, JOHN A. JOHNSON, a citizen of the United States, and a resident of Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Sulky-Frames; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a plan view of my improved sulky-frame, with dotted lines showing the thills moved together for the attachment of a double team 5 and Fig. 2 is a longitudinal vertical sectional view taken on the line x x in Fig. 1.

The same letters refer to the same parts in both the figures. Y

This invention relates to that class of sulkyframes which are used in agricultural implements-such as horse hay-rakes, sulky-cultivators, and the like-in which the thills are made adjustable, Snc., so that when it shallbe necessary or desirable to attach a double team instead of a single horse the said thills may be moved together so as to constitute a tongue, thereby effecting a saving not only in material, but also in the time required for making the :necessary changes and adjustments.

The detailed construction and arrangement of the parts constituting my invention are as will be hereinafter more fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A designates the axle of my improved sulky-frame, and B is a cross-bar arranged in front of and parallel to the same and connected to the axle by means ci' braces C O, secured on top ofthe said axle and cross-bar and converging toward their front ends, as shown.

D is another cross-bar, arranged intermediately between and parallel to the axle A and cross-bar B, and bolted or otherwise secured on top of the braces C G. In this manner a stiff, rigid, and durable frame is constructed.

E E designate the thills, which are of the ordinary construction and secured to the crossbars B and D, adjoining the braces C C by (No model.)

means of bolts or in any suitable manner. When bolts are used for the attachment of the thills, I prefer to secure them by means of thumb-nuts, in order that they may bereadily detached when required, although this is not indispensable, as ordinary nuts may be used. The thills E E extend in rear or' the cross-bar D, and are provided with supplemental perforations or bolt-holes, enabling the said thills to be moved forward or lengthened, if required. The cross-bars B and D are also provided with supplemental bolt-holes near the middle, for the attachment of the thills when thelatter are moved together, the holes in the cross-bar B being enough closer together than thosein D as to cause the front ends ofthe thills to touch each other while the rear ends are separated, thus causing one thill to brace the other and make a stronger tongue than if the thills were parallel, unless they are bolted together at their ends, thus requiring an eX- tra piece of mechanism. By placing the holes to each side of the center of the cross-bars B and D, and on an oblique line with the center, either one of the thills can be set in without changing the remaining thill, thus enabling the horse to be hitched to either side, instead of directly in front, to accommodate the driver or for bunching grain that has been .cut and laid in a swath, and the like.

The operation and advantages of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. Vhen the thills are attached to the sulky-frame adjacent to the braces C C, the lap-joint thus formed of the thills and braces insures great strength and rigidity to the device. Vhen it is desired to attach a double team, the thills are moved to the position shown in dotted lines in Fig. 1, when they will practically form a tongue of the kind and construction generally employed in this kind of devices.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States As an improvement in sulky-frames, a rigid frame having forwardly-convergin g side pieces and parallel cross-pieces, said cross-pieces being provided with four series offorwardly-converging adjusting-holes, two of said series of holes being to the right of the center of the In' testimony that I claim the foregoing as orosspieees and two being to the left, in commy own I have hereunto affixed my signature bination with it pair of adj ustabie thills, each in presence of two Witnesses.

thill being provided with a series of adjust- JOHN A. JOHNSON. 5 ingho1es by which they can be adjustably se- -W'itxiesses cured upon said eross-pieces, substantially as Y W. R. BAGLEY,

and for the purpose set forth. M. W. KRUEGER.
